① keep the installation site dry, the temperature is not less than 10℃, and the maximum humidity change value after installation should be controlled in the range of 40% ~ 60%. The installation site must meet the above temperature and humidity standards at least 24 hours before installation.
② Before installing the sound-absorbing board, check the model, specification, size and quantity of the sound-absorbing board to avoid various problems during installation. The sound-absorbing board must be placed in the place to be installed for 48 hours in order to adapt to the indoor environment and finalize the design.
③ the wall covered by sound absorption board must be installed according to the design drawing or construction drawing requirements of the keel, and the keel leveling treatment, the surface of the keel should be smooth, no rust deformation.
④ the structural wall should be processed before construction according to the building code, and the size of the keel layout must be compatible with the layout of the sound-absorbing board. Wooden keel spacing should be less than 300mm, light steel keel spacing should be less than 400mm. Keel installation should be vertical with the length of the sound-absorbing board.
⑤ usually the distance from the surface of the wooden keel to the base should be determined according to specific requirements, generally 50mm. The margin flatness and verticality error of wooden keel should not be greater than 0.5mm to avoid affecting installation.
⑥ keel clearance if the need to fill, then it should be installed in accordance with the corresponding design requirements, processing, and to ensure that it will not affect the installation of the sound absorption board behind.
① first measure the wall size, confirm the installation position, horizontal and vertical lines and wire sockets, pipes and other objects cut space reserved size. According to the actual size of the construction site calculation, and cut part of the sound-absorbing board and lines, and for wire socket, pipe and other objects cut empty reserved. If the opposite side has symmetry requirements, especially to pay attention to the size of the partial sound-absorbing board, to ensure the symmetry on both sides; Lines mainly include receiving line, outer corner line, connecting line.
②installation of sound-absorbing board: the installation sequence of sound-absorbing board should follow the principle from left to right and from bottom to top. When the sound-absorbing board is installed horizontally, the notch is upward; When installed vertically, the notch is on the right side. Partial real wood sound-absorbing board has pair of decorative pattern requirement, its each elevation should make up good number according to sound-absorbing board beforehand in turn from small to large undertake installation. And the number of sound-absorbing board also should follow from left to right, from bottom to top, number in turn from small to big order.
③ sound-absorbing board on the keel fixed: wooden keel with nail installation. The sound-absorbing board is fixed on the keel with shooting nails along the toning and groove of the board. Shooting nails must be more than 2/3 embedded in the wooden keel, and must be evenly arranged, and requires a certain density. The number of shooting nails connected with each sound-absorbing board and each keel is not less than 10. The sound-absorbing board is installed horizontally with the concave upward and installed with installation accessories. Each sound-absorbing board is connected in turn. When the sound-absorbing board is installed vertically, the notch is on the right, and it is installed in the same way from the left. Two sound-absorbing board end must leave not less than 3mm gap.
Note the installation of sound-absorbing board
Sound absorption board installation should pay attention to paint color difference, solid wood veneer sound absorption board color difference is a normal phenomenon. There may be color differences between the paint finish of the sound-absorbing board and the hand-painted finish of other parts of the installation site. In order to keep the paint color consistent, it is suggested to adjust the color of other parts of the manual paint according to the prefabricated paint color of the sound-absorbing board after installation; Or can advance request, by the manufacturer to provide without prefabricated paint treatment of solid wood veneer sound-absorbing board. In addition, it should be noted that the sound-absorbing board must be sealed and moisture-proof when stored in a non-installation environment.
